MACHINE FOR APPLYING GLUE T6 TOP DRAWING-ROLLS OF SPINNING-MACHINES.

.UPECIPICA'IIQN forming part of Letters Patent No. SOGAlQ, dated October14, 1884.

Application filed May 19, 1882. (No model.)

in Machines for Applying Glue to the Top DrawingBolls of Spinninglllachines, of which the following is a specification, reference beinghad to the accompanying drawings, forming a part thereof.

The object of my invention is to provide a machine by which glue may berapidly and evenly spread onthe surfaces of the top drawing-rolls usedin cotton-mills, to'prepare them for the reception of the cloth coveringwhich is to be applied thereto.

In the drawings, Figure l is a plan view of a machine embodying myinvention, and Fig. 2 a transverse section of the same.

A is a glue boX or reservoir, and B a hollow gluing roll or cylinderarranged within said reservoir, and having a cloth covering, b, saidcylinder being carried by heads 0, having journals 0 projecting outwardthrough plates I, having hollow hubs or sleeves 2 arranged in slots a inthe ends of the said box, said hubs affording bearings for saidjournals. The ends of the cloth-covered cylinder B are in close contactwith the plates I, so that the liquid glue in the reservoir cannotescape be tween the said plates and the ends of the cylinder. Thesleeves or hubs i affording bearings for the journals 0 are verticallyadjustable in the slots at, and are held in any position to which theymay be adjusted by set-nuts i. This vertical adjustment of thebearingsfor the journals of the cylinder 13 enables said cylinder to bemore or less deeply immersed in the glue contained in the reservoir, asmay be desired.

D is a scraper for removing the surplus glue from the cylinder B, saidscraper being preferably in the form of a roll, as shown, turning byfrictional contact with the said cylinder B. This serapingroll issustained by bearingpieces d, having flattened shanks (I provided withslots cl, through which and the ends of the reservoir pass screws d,fitted with setnuts d". By means of this construction the scraper may beadj ustably secured to the inside of the glue-reservoir, thereby beingcapable of being moved toward or from the gluin g-cylinder, ascircumstances or different sizes of gluing-cylinders may require.

E is a roller for supporting the drawingrolls to be coated with glue.This supporting roller E is arranged on the side of the gluing cylinderopposite to the scraper, and is sup ported by brackets e, in which thejournals 6 of the said roller have their bearings. The brackets e areprovided with slots 0, through which and the ends of the reservoir passscrews e having set-nuts 6 The brackets e and the roller E carriedthereby are thus capable of being adjusted toward or from thegluing-cylinder B, so as to vary the space between said cylinder androller.

F indicates a drawing-roll supported by the roller E and held by gravityin gentle contact with the gluing-cylinder so to be coated with glue, asthe latter revolves, preparatory to re ceiving the cloth covering whichis to be stuck on by the glue. The roller E is placed a sufficientdistance from the gluing-cylinder to cause the drawing-rolls supportedby said roller to incline toward the said cylinder and to be held ingentle contact therewith by gravity, as will be readily understood byreference to Fig. 2.

The operation of my invention will be read ily understood from theforegoing: The parts being assembled as shown in the drawings, and theglue-reservoir being partly filled with liquid glue, (which may be keptwarm by any suitable means,) the drawingrolls to be coated therewithwill be placed on the supporting roller E in contact with thegluing-cylinder. The latter, being partly immersed in the liquid glue,will, when rotated, spread the gluesmoothly and evenly on the surfacesof the drawingrolls, (supported in frictional contact with said cylinderand thus rotated thereby,) the warm surface of the gluing-cylinder, keptheated by the warm glue, imparting sufficient heat to the drawing-rollsto cause the glue to spread properly thereon.

Having thus described my invention, I claim and desire to secure byLetters Patent 1.
